2 Claims. 1

The invention relates to window constructions which are provided with auxiliary or storm sashes designed primarily for use during the winter season. Such auxiliary windows would also be useful throughout the entire year were it not for the inconvenience of manipulating two sashes whenever the window is opened for ventilation or for any other purpose. It is therefore the object of the instant invention to obtain a construction with which the raising of the main window sash will simultaneously effect the raising of the auxiliary sash if this is desired, or on the other hand will permit the independent operation of these sashes.

To this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Fig. 1 i a vertical section through a portion of a window of my improved construction;

Fig. 2 is a horizontal section on line 2-2, Fig. 1;

Fig. 3 is a sectional perspective view illustrating the coupling between the main and auxiliary sashes which causes them to rise and fall together;

Fig. 4 is a vertical section through one side of the auxiliary sash illustrating an automatic holding means therefor; and

Fig. 5 is a perspective view of the several elements constituting the coupling means.

As illustrated, A is the lower sliding sash of the main window which is shown seated on the sill B. C is the lower sash of the auxiliary or storm window, which is seated on the auxiliary sill D resting on the main sill. As heretofore constructed, these main and auxiliary sashes are independent of each other and must be separately manipulated. Thus if it is desired to raise the sash A for purposes of ventilation, it is also necessary to independently raise the sash C and, in the same way, the closing of the two sashes must be separately performed. To render it possible to operate both sashes as a unit, I have provided a coupling of the following construction. E is a plate member secured to the outside of the lower rail of the main window sash by suitable fastening means such as screws F. This plate is provided with a return bent portion E, which forms a vertically extending bearing for a rod G. The rod G has a laterally extending arm G of a length to bridge the space between the lower rails of the sashes A and C. However, it may be turned back into parallelism with the rail of sash A when the two sashes are uncoupled. H is a member which may be secured. to the inner side of the lower rail of the sash C by means of a single screw I. The member H has return bent flanges H, H at itsupper and lower ends which extend towards each other in the same plane but with sufiicient space therebetween for the passage of the arm G.

engaging the arm G andholding it from displacement. With the construction as above described, whenever it is desired to have the windows operate as a unit both sashes A and C are slightly raised to provide sufficient space for the insertion of a hand to turn the arm G from its position parallel to the sash into an outwardly extending position and into engagement with the notches H of the member H. Thus if the sash A is raised, the upper flange H will be in the path of the arm G, thereby raising the sash C. In the same manner, the lowerin of the sash A will cause the arm G to engage the lower flange H of the member H drawing down with it the auxiliary sash C.

Sliding window sashes are usually counterbalanced, and the weights used substantially equal the weight of the sash. Thus if the weight of the auxiliary sash is added, this might destroy the balance with the result that the windows would not remain in the adjusted position. This difficulty I have overcome by providing a one-way clutch holding device for retaining both sashes from dropping from each position of adjustment thereof. Various constructions of holding means for the sash C may be used and that illustrated in Fig. 4, which specificallyis not a part of the instant invention, is only one construction suitable for the purpose. However, as shown, the sash C has a groove J in a side rail thereof and an arm K pivotally attachedto the window frame extends into this groove. The length of the arm K is such that it must assume either an upwardly or a downwardly inclined position when engaged with the grooves and its free end is provided with teeth K, which will bite into the sash and hold it against movement in one direction. Thus if the member K is inclined upward the sash C may be freely raised but cannot be lowered for the teeth K will hold it against movement in this direction. An operating rod L extends downward from the member K, so that by raising this rod it will disengage the lock and permit the lowering of the sash.

My improved construction makes it feasible to retain the storm windows throughout the summer, as well as the winter season. This has the advantage first that it provides better thermal Each of these flanges is also provided with a V-shaped notch H forinsulation against external heat; and, second, that it excludes dust and dirt from access to the main window or from accumulating on the sill thereof. It also protects the main window and the window sill from the weather, which preserves the paint and saves the putty on the glass from cracking and falling off. On the other hand, it does not interfere with the raising of the main sash whenever desired and without the necessity of manipulating the auxiliary sash.

What I claim as my invention is:

1. In a window construction, parallelly arranged main and auxiliaryslidable 'sashesand coupling means therebetween comprising, a plate member secured to the outer iaceflof the'lower rail of the main sash fashionedto form a vertically extending bearing, arod member having a vertical portion engagingsaid bearing and a lateral portion bridging the space between said sashes when turned outward, and a member secured to the inner iace of the lower rail of the auxiliary sash slotted to receive the outer end of said ,rod member, I

2. In a window construction, parallell-y arranged main and auxiliary slidable sashes and coupling means therebetween comprising, a plate member secured to the outer face of the lower said member being adapted to receive the outer end of said rod member.
